Your children were very privileged to be exposed to traveling while they were growing up. I think it gives children a great advantage to have that kind of experience.
Yes, sadly the world is not as cool a place anymore. But once again, I think this is where it is a good thing that your children got exposed to traveling at a young age and they are well-rooted now. I believe that because of this, you can have more peace of mind as a parent, knowing that they are experienced and will not easily fall into some traps due to ignorance. That's just my opinion...
